Pump 4, heater 2, boiler 1 and steam turbine 11 are sequentially connected；Steam turbine 11 separates two-way, all the way 7 bottom of connection spray combined column,
Another way connects Air-Cooling Island 12；7 bottom of combined column connection water storage water seal 6 is sprayed, water storage water seal 6 connects heat-exchanger pump 5, heat-exchanger pump 5
Connect oxygen-eliminating device 3；Air-Cooling Island 12 connects hot well 9；Spray the top connection vacuum pump 10 of combined column 7；The connection spray of Air-Cooling Island 12
7 middle part of combined column.
The top of spray combined column 7 is provided with normal pressure and temperature note desalination water installations.Battery limit (BL) tyre normal pressure and temperature demineralized water is from spray
Drench 7 top spray of combined column and under.
Hot well 9 is connected with condensate pump 13, and condensate pump 13 connects oxygen-eliminating device 3.Spray combined column 7 for spray column with it is board-like
Tower combined column, heat exchange mainly carry out on column plate, and two-way steam exhaust is balanced by tower weir plate height.

Air-cooled end enters spray combined column 7 containing not condensing steam exhaust, and the low temperature demineralized water with being injected by tower top exchanges heat,
Tower top is risen to air-flow, steam exhaust is all condensed into liquid by heat exchange and is fallen by gravity to bottom of towe, no containing not condensing steam exhaust
Condensing is by tower top pipe by vacuum pumped；Vertical tube introducing steam exhaust is risen by air-cooled steam exhaust and enters tower leaching combined column, with low temperature
The middle warm water that demineralized water obtained after heat exchange heat exchange exchanges carries out heat exchange by spraying the board-like column plate in combined column 7,
Condensing does not rise to tower middle and upper part and carries out exchanging cooling again, eventually by tower top pipe by vacuum pumped.
The high temperature demineralized water carried out after heat exchange with not condensing is supplied to boiler replenishing water and user by centrifugal pump.
